Tracked suspension beam assembly

An elongated beam assembly for a tracked suspension, the beam assembly having front and rear portions, the beam assembly comprising:

• an inverted “U” shaped member, the inverted “U” shaped member further comprising generally vertical inner and outer walls, the inner and outer walls each having inner and outer surfaces, the inner and outer walls each having a top edge, the inner and outer walls are coupled together by a curved plate adjacent the rear portion, wherein the curved plate has a top and bottom surface and inner and outer lateral edges, wherein the inner lateral edge is coupled to the outer surface of the inner wall and the top edge of the outer wall is coupled to the bottom surface of the curved plate such that the outer lateral edge extends laterally outward beyond the top edge of the outer wall;
• a plurality of track wheels coupled to the bottom of the member and disposed inside the member;
• and
• a drive wheel mounting plate having an opening for mounting of a drive wheel and a curved edge portion, the drive wheel mounting plate is coupled to the curved plate such that the curved edge portion extends along the top surface of the curved plate and that the drive wheel mounting plate extends substantially perpendicular from the top surface of the curved plate.
